Screening of Granulated Catalysts for Dehydrogenation of Light C4 Paraffins

Abstract

Under discussion are methodological aspects of the screening of granulated aluminochromium catalysts for dehydrogenation and methods for estimation of their operation lifetime based on the catalyst treatment in a steam-air medium. The practicability of small size reactors (with the diameter no less than four effective granule sizes) for comparing the catalyst activity at the screening stage are demonstrated with Mg- and Zr-promoted aluminochromium catalysts as an example.
